check-raise the flop next time either min-raise or a little more, you'll get more information about his hand that way. I tend to check-raise bottom and middle set in these spots (where there was no preflop action). If I get 3 bet I'm either up against a bigger set or a huge draw and can just toss my hand for 2 or 3 dollars knowing I made the right play instead of tossing in a buck and second uessing myself for 10 hands.
